1 Polonium 210
By;jackson Polonium 210

2 Physical properties of polonium.
Is has been known to be a light silver Melting point: K Boiling point: 1235 K Density ; 293 K: 9.4 g/cm3

3 Crystalline Structure of Polonium
Crystalline Structure –simple cubic or primitive.

4 Atomic number, atomic weight, number of protons,
Symbol-PO Isotopes: 29 Atomic number- 84 Atomic weight- 209 Number of protons/electrons- 84 Number of neutrons- 125

5 Polonium Group-Metalloids block- p-block
electron configuration- [Xe] 4f14 5d10 6s2 6p4 Period-6

6 Polonium`s common uses
Polonium has attracted the attention to be used as a light weight heating source. It is used on brushes to remove dust from photographs.

7 More common uses Also used as a trigger for nuclear weapons.
It can be used in machinery in textile mills to remove static charges. Polonium can be alloyed or mixed Beryllium to provide a source of neutrons.

8 Polonium`s abundance and places to find it.
Polonium is rarely found in nature and has been described as scarce and excessively rare. It is made in very small quantities through a nuclear reaction of bismuth. Neutron irradiation of 209bismuth (atomic number 83) gives 210polonium (atomic number 84). It is found in uranium ores, but none extract it form these ores.

9 Reactivates and Oxidationstates
Polonium dissolves in concentrated hydrochloric acid, HCl, sulphuric acid, H2SO4, or concentrated nitric acid, HNO3, initially to form solutions containing Po(II). Oxidation states: +2, +4 Polonium reacts under controlled conditions with the halogens chlorine, Cl2, bromine, Br2, and iodine, I2, to form the respective tetra halides polonium(IV) chloride, polonium(IV) bromide, and polonium(IV) iodide.

10 Facts Polonium has more isotopes than any other element, all of which are radioactive. Polonium dissolves readily in dilute acids, but is only slightly soluble in alkalis.
